Complex Percutaneous Coronary Intervention: The Treatment of Chronic Total Occlusions, Ectatic Infarct Related Arteries, Bleeding Outcomes after Percutaneous Coronary Interventions in Octogenarians and Bifurcation Lesions in ST Elevation Myocardial Infarction.

The unifying hypothesis of this body of research is that complex coronary intervention can be performed safely and effectively. It emphasizes that this can be achieved by a specific subset approach. 1.With systematic adaption of newer procedural techniques by establishment of dedicated CTO program, CTO-PCI can be performed safely. 2. Stenting ectatic infarct related arteries when feasible results in better clinical outcomes. 3. Pre procedural judicious usage of bleeding score systems, to rationalise the use of blood thinners keeps bleeding rates at low level during PCI in the elderly 4. Bifurcational primary angioplasty has increased events at 1 year, which could be improved with increased usage of radial approach and newer antiplatelets.
